Header, Intake, & Exhaust - exhuast help

Hey, I was wondering....I have a HX, and i want a cat back...but they only dang company that i can find that makes one for the HX is Pacesetter....are they any good? should i go with them?? could i get an exhuast for a different trim of civic (like the EX) and it still fit/work properly??

you can go to any muffler or performance shop and have a custom exhaust made. I wouldnt really recommend pacesetter though.
